Abstract

Essential oil of the flowers of Azadirachta indica was obtained at 0.001% yield by steam distillation. It mainly consisted of α-cubebene (3.04%), copaene (7.03 %), humulene (3.7 %), δ-cadinene (9.43 %) and a number of sesquiterpenes. The oil also contained a series of unidentified organosulphur compounds. These
organosulphur compounds were picked up by the S³⁴ isotope. The oil exhibited antimicrobial activity against Bacillus subtilis (ATCC 6633), Candida albicans (ATCC 10231) and Microsporum gypseum (Clinical isolated).
